Joss Whedon on the future of TV:

"The networks will all be creating exciting, innovative new spin-offs of today's shows. Approximately 67 percent of all television will be CSI-based, including CSI: Des Moines, CSI: New York but a Different Part than Gary Sinise Is In and NCSI: SVU WKRP, which covers every possible gruesome crime with a groovin' '70s beat."
